The increasing number of alternative power sources like solar, wind driven or biological energy systems call for consistent and well demanding regulations for energy feed into the utility grid. Manufacturers of such systems have to test and to prove the compliance of their equipment. Grid simulators form an electronic equivalent circuit for the grid, but allow to vary all relevant parameters in order to test the behaviour and response of the equipment under test.
